It's metric - M12x1.75. I used one of these as a shifter handle:

^^^ These are the kind of solutions I like, they don't have the "Viper tax" added.

GRADE 8 OR 5 BOLT? the newer ipsco ones come with the sealing ring for the environmental boot, you will want to try to seal that up to reduce fumes

Yes, either grade 5 or 8, you want a hardened bolt/stud. On mine, I slid a short piece of fuel line on the stud, then a short piece of heater hose over that to provide the seal to the lower boot. I also zip tied the boot to the heater hose.
